[PATCH] assorted kdev_t cleanups in filesystems

[Alexander Viro]

	* JFS uses its ->logdev only twice - one of the places assigns
it to_kdev_t(le32_to_cpu(...)), another uses kdev_t_to_nr() of it.
Switched to u32 - it's just a place where we store device number we'd got
from superblock.
	* several reiserfs_fs.h function prototypes removed - functions
in question don't exist anymore.
	* smbfs doesn't support device nodes; ->f_rdev removed.
